Australia CGT & Negative Gearing Changes 2027

The Australia Budget 2026-27 tax package proposes two major investor changes from 1 July 2027: a reform of negative gearing for residential property and a reform of the capital gains tax discount. The official Budget materials were released on Tuesday, 12 May 2026. They use a specific Budget-night cutoff: 7:30pm AEST on 12 May 2026. That time matters most for established residential investment properties.

For negative gearing, the proposed rule is targeted at residential property. Established residential properties acquired before the cutoff are protected from the negative gearing change until they are sold. Established residential properties acquired from that cutoff are scheduled to move into the new restriction from 1 July 2027. Under that restriction, losses from affected established residential properties would be deductible against residential property income or residential property capital gains, not against broader income such as salary and wages. Unused losses would be carried forward.

For CGT, the reform is broader. Budget Paper No. 2 says the 50 per cent CGT discount will be replaced by cost base indexation for assets held for more than 12 months, with a 30 per cent minimum tax on net capital gains. The CGT changes are proposed to apply to all CGT assets held by individuals, trusts, and partnerships, with transitional arrangements so that the new treatment applies only to gains arising after 1 July 2027. Investors in new residential properties are expected to be able to choose either the 50 per cent discount or the new arrangements.

Treat this as an official Budget guide, not as a completed personal tax assessment. The Treasury Ministers media release says the Government will introduce legislation and consult on implementation details. A property investor should therefore use this page to map the official dates, classify affected assets, prepare records, and decide what questions to ask a tax adviser before buying, selling, refinancing, or restructuring.

The timetable below is the core planning map. It separates the Budget-night cutoff from the 1 July 2027 start date because those dates do different jobs. The cutoff decides whether an established residential property is protected from the negative gearing change. The start date decides when the proposed negative gearing and CGT systems begin to operate.

The most common mistake is treating 12 May 2026 and 1 July 2027 as if they are the same date. They are not. A post-Budget-night buyer of an established property does not automatically lose all current treatment on 13 May 2026. The Budget papers point to 1 July 2027 as the start of the new negative gearing restriction. But the purchase date after 7:30pm AEST on 12 May 2026 determines whether that property is inside the affected cohort once the start date arrives.

The second common mistake is assuming the CGT change is only a landlord rule. It is not. The Budget Paper No. 2 receipt measure describes a capital gains tax change across CGT assets held by individuals, trusts, and partnerships. Rental housing is politically central to the reform, but the CGT mechanics are wider than residential property.

The Budget package is not just a date change. It is part of a housing and tax policy package with official estimates about investor lending, rent, house prices, owner occupancy, CGT use, and Budget receipts. These numbers should not be used as a promise about any individual suburb or property, but they explain why the Government framed the reform around existing housing, new builds, and real capital gains.

The data points can pull investors in opposite emotional directions. On one hand, the official modelling says the expected rent impact is small and that the transition rules reduce the incentive to rush into transactions. On the other hand, the reform can still materially change the after-tax picture for a specific highly geared investor, a trust structure, or a long-held asset with large post-2027 real gains. The planning answer is therefore not to panic and not to ignore the change. The answer is to model your actual property, debt, income, holding period, and sale assumptions.

Budget Paper No. 2 also lists related payment amounts for the Australian Taxation Office, Treasury, and the Digital Transformation Agency. That matters because a tax reform this large is not only a headline policy. It requires systems, guidance, forms, data matching, compliance design, and taxpayer education. Investors should expect more ATO and Treasury detail before the rules are fully operational.

Negative gearing is not a special form that makes a bad investment good. It is the tax effect that can arise when deductible costs connected to an income-producing investment exceed the income from that investment. In rental property, the practical issue is usually interest, rates, insurance, repairs, management fees, land tax, body corporate costs, and other allowable rental expenses compared with rent. If deductible rental expenses are higher than assessable rental income, the property has a tax loss.

Under current broad settings, many individual property investors can use that loss against other assessable income, such as salary and wages, assuming the expenses are properly deductible and the property is rented or genuinely available for rent. The Budget 2026-27 proposal narrows that outcome for affected established residential properties from 1 July 2027. The proposed rule does not say that losses disappear. It says they are ring-fenced to residential property income and residential property capital gains, with excess losses carried forward.

The policy distinction is established housing versus new housing. Existing arrangements remain unchanged for properties held before the Budget-night cutoff. Eligible new builds are also protected because the Budget wants tax support to flow toward housing supply. The affected group is post-cutoff established residential property. This means a buyer who acquires an existing dwelling after the cutoff should model the investment without assuming that the annual rental loss can reduce salary tax after 1 July 2027.

Ordinary rental property rules still matter. The ATO rental property guidance separates expenses that can be claimed now, expenses claimed over several years, and expenses that cannot be claimed. The ATO interest guidance also focuses on the use of borrowed funds. If a loan is redrawn or refinanced and part of the money is used for a private expense, the interest needs to be apportioned. A reform about negative gearing does not override those ordinary deductibility rules.

That is why serious investor modelling should use two layers. First, determine the real rental result under ATO rental income and expense rules. Second, apply the reform lens: is this property pre-cutoff, post-cutoff established, or an eligible new build? Only after those two layers are separated can you decide whether the change affects annual cash flow, tax instalments, borrowing capacity, or the value of the investment to you.

The capital gains tax reform is built around a different idea: taxing real gains rather than giving a flat 50 per cent discount. The current ATO CGT discount page explains the existing rule for many individuals: if an eligible asset has been owned for at least 12 months and the taxpayer is an Australian resident for tax purposes, the remaining capital gain can generally be reduced by 50 per cent before it is reported in the income tax return. The Budget proposal moves away from that flat discount for future gains.

From 1 July 2027, Budget Paper No. 2 says the 50 per cent discount will be replaced by cost base indexation for assets held for more than 12 months, with a 30 per cent minimum tax on net capital gains. In plain language, indexation adjusts the cost base for inflation, so the taxable gain is closer to the real gain rather than the nominal gain. The 30 per cent minimum tax then prevents very low tax outcomes on realised gains after indexation has been applied.

The transition rule is the key investor protection. The Budget papers say the new CGT arrangements apply only to gains arising after 1 July 2027. The 50 per cent discount continues for gains arising before that date, and pre-1985 gains before that date remain exempt. In practice, investors should expect the final law and ATO guidance to tell them how to document the split between pre- and post-commencement gains. A market valuation file around 1 July 2027 may become a central record for long-held assets, although the precise workflow should be confirmed once legislation and guidance are released.

The CGT change affects more than landlords. Budget Paper No. 2 says it applies to all CGT assets, including pre-1985 CGT assets, held by individuals, trusts, and partnerships. That can include investment properties, shares, managed funds, crypto assets, business assets, and other assets that sit inside the CGT system. Companies have different tax treatment, and complying superannuation funds have their own settings, so ownership structure matters.

New residential properties receive a special policy treatment. The Budget tax reform page says investors in new builds will be able to choose the 50 per cent CGT discount or the new arrangements. That choice can matter because indexation and a minimum tax do not always beat the old discount. A high-inflation, low-real-gain case may look better under indexation. A high-real-gain case may look better under the old discount, depending on the final law, marginal tax rate, losses, and ownership structure.

The safest way to read the reform is by asset, acquisition timing, and owner type. A person who already owns an established rental property before the Budget-night cutoff is not in the same position as a person who buys an established rental property in 2027. A person buying an eligible new build is not in the same position as a person buying a decades-old apartment. A salary earner holding shares personally is not in the same position as a business using a company or a family using a discretionary trust.

The negative gearing reform is narrower than the CGT reform. It focuses on residential property losses, not every investment expense in the economy. The CGT reform is broader because it changes how future capital gains are taxed for individuals, trusts, and partnerships. The discretionary trust reform is separate again and starts later. Readers should avoid blending all three into one simplified rule.

The family home is a special case. The Treasury Ministers tax reform release says the changes will not alter tax arrangements for the family home. That does not mean every property someone calls a home is automatically outside CGT forever. ATO main residence rules still need care when a property is rented out, used partly for business, owned by a foreign resident, inherited, held on land over the usual threshold, or treated as a former main residence under the absence rule.

Income support recipients also receive a specific CGT minimum-tax note in Budget Paper No. 2. It says income support payment recipients, including Age Pension recipients, will be exempt from the minimum tax. That does not mean every capital gain is tax-free. It means the minimum-tax layer is not intended to apply to that group, subject to final law.

Use the table below as a first-pass classification tool. It is not a substitute for professional advice, because final legislation can define terms and exceptions more precisely than Budget media. It does, however, show the official direction of travel and where most investor questions should start.

Notice that the answer often changes across the same asset. A pre-cutoff established rental can keep existing negative gearing treatment while also needing a CGT transition calculation for gains after 1 July 2027. A post-cutoff established rental can have one treatment before the start date and a different loss treatment after the start date. A new build can remain favoured for both negative gearing and CGT choice, but investors still need to confirm what counts as an eligible new build once detailed law is available.

The short answer is: not solely because a headline says the deadline is coming. The official tax explainer says the transitional arrangements are designed to minimise risks of asset market disruption. It also says only capital gains accrued after the commencement date are subject to the new arrangements. That framing is important because it undercuts the simplest fear-based version of the story: "sell everything before 1 July 2027 or lose the whole discount." That is not how the official material describes the transition.

A sale can still be rational. It may make sense if the asset already fails your investment test, if the debt burden is too high, if repairs are large, if the tenant risk is rising, if land tax or insurance changes have hurt the numbers, if a better use of capital exists, or if you need liquidity. But those are investment and cash-flow reasons. The tax reform should be one input in the sale model, not the whole decision.

A rushed sale can also destroy value. Selling property usually means agent commission, advertising, conveyancing, potential break costs, vacancy timing, discharge fees, moving portfolio allocations, and the risk of buying back into a market with transaction costs. If the property is a strong long-term asset, selling just to avoid uncertainty can be more expensive than holding through reform. Conversely, if the investment only worked because salary income absorbed the annual rental loss, the post-2027 cash-flow model deserves a hard look.

A practical sell-or-hold model should include at least four versions: current law, Budget reform base case, higher-rate stress case, and lower-growth stress case. Include rent, vacancy, repairs, interest, insurance, land tax, property management, capital works, depreciation, expected sale price, selling costs, loan balance, and likely tax. Then ask whether the decision still works if the tax outcome is worse than expected or if the property market does not behave as forecast.

The most valuable action before 1 July 2027 may not be buying or selling. It may be record-building. Transitional tax systems usually reward clean records because the taxpayer needs to prove dates, cost base, ownership, use, loan purpose, income, expenses, and sometimes market values. If you cannot prove a fact later, the practical value of that fact can fall sharply.

For property, save the contract, settlement statement, stamp duty records, legal costs, buyer agent fees, improvements, depreciation schedules, borrowing costs, refinance documents, rental statements, insurance records, council rates, strata records, land tax, repairs, capital works invoices, and sale-related costs. For loans, preserve evidence of what the borrowed funds were used for. The ATO interest expense guidance is clear that the use of borrowed money matters when deciding interest deductibility.

For CGT transition planning, investors should watch for guidance on valuation or apportionment around 1 July 2027. The Budget papers say gains before the date retain old treatment and gains after the date move to new treatment. That implies a need to separate periods or values. The final law may provide a specific method. Until then, investors should avoid informal spreadsheet-only records where significant gains are involved.

For shares, managed funds, and other non-property assets, keep acquisition records, corporate action records, dividend reinvestment records, brokerage statements, cost-base adjustments, and exchange-rate records where relevant. The CGT reform is broad enough that property investors are not the only people who need to prepare.

Calculators cannot decide the law, but they can force discipline. Start with the Australia Income Tax Calculator to understand the tax-rate context for salary, rental income, and other taxable income. Then use the Rental Property ROI, DSCR, Cap Rate, and Cash-on-Cash Calculator to separate operating performance from tax treatment.

Next, use the Capital Gains Tax Calculator to model sale-price sensitivity. You may need to run several versions because final Australian rules for post-2027 indexation and minimum tax will need jurisdiction-specific treatment. The current calculator can still help with the logic of sale proceeds, cost base, losses, holding period, and tax-rate sensitivity.

If the question is whether to buy a home or keep renting, use the Rent vs Buy Calculator with conservative inputs. The Budget is explicitly framed around shifting more households into home ownership, but an individual rent-vs-buy decision depends on deposit, borrowing capacity, mortgage rates, strata, insurance, repairs, stamp duty, opportunity cost, job stability, family plans, and location risk.

Finally, use the Mortgage Calculator and Inflation Calculator for supporting assumptions. Indexation makes inflation more visible in the CGT discussion, but inflation also affects rent, wages, maintenance, insurance, rates, and replacement costs. A property model that assumes rent rises but ignores expense inflation is not a serious model.

The most important official written sources are the Budget tax reform page, Budget Paper No. 2, the negative gearing and CGT tax explainer, the Budget overview, and the Treasury Ministers media releases. The media releases are useful because they state the policy in plain language: negative gearing for residential property is limited to new builds from 2027-28; existing arrangements remain unchanged for investments made before the Budget cutoff; the 50 per cent CGT discount is replaced from 1 July 2027 by inflation-adjusted indexation with a 30 per cent minimum tax; and family home and superannuation tax arrangements are not changed by this reform package.

CalculatorWallah reviewed current official government and institutional video sources for a dedicated Budget 2026-27 video explaining the negative gearing and CGT reform. A clean official video solely about this reform was not found during this update. Because the article rules prefer official or institutional videos and avoid unrelated creator clips, this guide embeds an official ATO rental-expense video instead. It is relevant to the deduction layer that negative gearing depends on, but it should not be treated as a Budget reform explainer.

The written government sources should remain the authority for the reform timetable until legislation, explanatory memoranda, Treasury consultation papers, and ATO guidance are released. If a later ATO or Treasury video directly explains the reform, this section should be updated with that official media.

The practical work starts now, not in June 2027. The goal is to be able to answer three questions without guessing: what asset do I own, when did I acquire it, and how will the proposed rule treat income, losses, and gains from that asset?

• Save the contract date and exact exchange time for every residential property acquired around Budget night.
• Classify each property as pre-cutoff established property, post-cutoff established property, or eligible new build.
• Separate rental income, interest, repairs, rates, insurance, management fees, land tax, depreciation, and capital works records by property.
• Keep loan-purpose evidence when refinancing or redrawing because ATO interest deductibility depends on use of borrowed funds.
• Plan for a 1 July 2027 market value or apportionment file if you expect to hold assets across the CGT transition date.
• Model sale proceeds after agent fees, legal costs, lender discharge costs, tax, replacement property costs, and debt reduction.
• Stress-test higher interest rates, lower rent growth, vacancy, repairs, insurance, land tax, and lower post-tax sale proceeds.
• Review trust, partnership, and individual ownership structures before the separate discretionary trust rules begin.
• Do not treat a social media summary or news headline as the final law; watch legislation, Treasury consultation, and ATO guidance.

A final caution: do not make a tax-only decision on incomplete law. The Budget documents are official and important, but they are not the final operational instructions for every taxpayer. If the dollar value is material, put the property or portfolio into a written advice workflow. The right adviser question is not "will tax go up?" It is "how does the proposed law change my after-tax cash flow, sale outcome, risk, and alternatives?"

The FAQ below repeats the most important operational points because many readers arrive through a single search result or news headline. For the legal answer, always check the final enacted law and current ATO guidance.
